Answer 1

Solution:

we have been asked to find

How much more time did Maria spend doing research ?

Maria spends doing research = 30%
and using email = 15% of a day (24 hours)

Time spent on research = 30% of 24 = $\frac{30}{100} *24= 7.2$

Time spent on checking email = 15% of 24 = $\frac{15}{100} *24= 3.6$

so, $7.2 - 3.6 = 3.6$

Hence , Maria spends 3.6 hours more on doing research than checking email.
